Firearm sight mount

Abstract

A firearm sight mount with a sight mount body configured for clamping on the outside of a firearm barrel. In one embodiment the sight mount has a unitary sight mount body that is split to permit the body to be slipped past any existing front sight on the firearm barrel. The split construction of the sight mount body permits it to be clamped to firearm barrels having different outside diameters and tapers. The other embodiments use a two piece body that are configured to be clamped to firearm barrels having different outside diameters and tapers and in one of these embodiments provision is made for the sight mount to fit around a rib on the barrel. In all embodiments, the sight mount body has a flat rectangular shaped mounting surface with short cylindrical projections sized and shaped to mesh with corresponding holes in the sight and hold the sight in place. Two screw holes are also provided in the mounting surface for holding the sight to the mounting surface. The use of only two screws reduces the number of screws that can work loose when the firearm is fired.

What is claimed is:  
     
       1. A firearm sight mount for attachment to the outer surface of the muzzle end portion of the barrel of a firearm comprising a sight mount body, mounting means on said sight mount body for mounting a sight to said sight mount body comprising a substantially flat mounting surface having a pattern of a plurality of projecting identical circular cross section cylindrical studs with the studs having a maximum height H above said mounting surface determined as follows: 
       
         
           H=D/2  
         
       
       Where D is the diameter of said circular cross section cylindrical studs  
       and attaching means on said sight mount body for attaching said firearm sight mount to the outer surface of the muzzle end portion of a firearm barrel. 
     
     
       2. The firearm sight mount for attachment to the outer surface of the muzzle end portion of the barrel of a firearm of claim  1  wherein said studs project at an angle of ninety degrees from said substantially flat mounting surface. 
     
     
       3. The firearm sight mount for attachment to the outer surface of the muzzle end portion of the barrel of a firearm of claim  2  wherein said substantially flat mounting surface is rectangular shaped. 
     
     
       4. The firearm sight mount for attachment to the outer surface of the muzzle end portion of the barrel of a firearm of claim  3  wherein said pattern of a plurality of projecting identical circular cross section cylindrical studs comprises four studs. 
     
     
       5. The firearm sight mount for attachment to the outer surface of the muzzle end portion of the barrel of a firearm of claim  2  wherein said firearm sight mount comprises a plastic material. 
     
     
       6. The firearm sight mount for attachment to the outer surface of the muzzle end portion of the barrel of a firearm of claim  5  wherein said plastic material comprises a glass filled urethane. 
     
     
       7. The firearm sight mount for attachment to the outer surface of the muzzle end portion of the barrel of a firearm of claim  6  wherein said attaching means on said sight mount body for attaching said firearm sight mount to the outer surface of the muzzle end portion of a firearm barrel comprises means for clamping said firearm sight mount to the outer surface of the muzzle end portion of the barrel of a firearm. 
     
     
       8. The firearm sight mount for attachment to the outer surface of the muzzle end portion of the barrel of a firearm of claim  7  wherein said clamping means for clamping said firearm sight mount to the outer surface of the muzzle end portion of the barrel of a firearm comprises means for enabling said firearm sight mount to be clamped to a firearm barrel having a sight on the muzzle portion thereof. 
     
     
       9. The firearm sight mount for attachment to the outer surface of the muzzle end portion of the barrel of a firearm of claim  7  wherein said clamping means for clamping said firearm sight mount to the outer surface of the muzzle end portion of the barrel of a firearm comprises means for enabling said firearm sight mount to be clamped to a firearm barrel having a sight rib. 
     
     
       10. The firearm sight mount for attachment to the outer surface of the muzzle end portion of the barrel of a firearm of claim  7  wherein said clamping means for clamping said firearm sight mount to the outer surface of the muzzle end portion of the barrel of a firearm comprises a non circular aperture for fitting around the outer surface of the muzzle end portion of the barrel of a firearm.
